Are you one of those people who taps at the bottom of an inverted ketchup bottle, waiting in frustration for the sauce to pour? I am speaking of traditional ketchup bottles, not squeeze tubes, wide-mouth jars, or bottles designed to stand on their heads. Have you ever wondered if there is a right way to do it – a way that works, and makes scientific sense?
Yes, folks, there is a right way to do it, and it does make sense. Here is how, and why:
…In order for the ketchup to emerge, air must enter the bottle….
So, in the case of the full ketchup bottle, the problem can be divided into two issues: (1) How can I get the ketchup to move aside, so that air can enter on the opposite side? (2) How can I give the ketchup "extra weight," so that it will be pulled out of the bottle faster?
The first issue is solved by holding the bottle sideways, with a slight downward tilt, rather than upside-down. In this position, the ketchup naturally is pulled to the lower side of the neck, and the air naturally will channel along the higher side of the neck. Anyone who pours an ordinary liquid from a bottle knows this. Yet it is amazing how the experience is forgotten when it comes to ketchup.
Merely holding the bottle in the correct position is not very effective. It is necessary to "increase the weight" of the ketchup by applying some G-force. This can be done by making a fist, and tapping the bottle downwards against the fist, to bring the bottle to an abrupt halt. Don't hurt yourself! If your hands are delicate, you may try some other method of applying an abrupt stop to the bottle, provided that the stop is not rigid or fragile, and that you mind where the ketchup is going to emerge. Striking the bottle at the upper side of the neck is much less effective, since it applies the G-force in the wrong direction.
Tapping the inverted bottom of a full bottle – the customary way – is counterproductive. If you do that, most of the G-force will tend to keep the ketchup in the bottle. But now you know the right way, thanks to the amazing power of the Internet to unleash this kind of information. Of course, it would be possible to print instructions on the side of the ketchup bottle, but you wouldn't read them if they were there, now would you?
